12V 24V PWM Fan Speed Controller with Temperature Control for PC Case Cooling Triple 4-Wire Output Intelligent Sync

12V 24V PWM Fan Speed Controller with Temperature Control for PC Case Cooling Triple 4-Wire Output Intelligent Sync Description

1. This speed controller supports 12V/24V 5A input (current determined by the connector's current-carrying capacity), with one input and three synchronized outputs. It is compatible only with for -standard 4-wire fans (2-wire and 3-wire fans are not supported).
2. Three independent 4-wire outputs for synchronized, intelligent control of three fans
3. Built-in high-precision temperature control module that detects temperature in real and automatically adjusts speed
4. Streamlined design with simple wiring, allowing users to get started quickly
5. DIP switches for setting temperature control thresholds; intuitive operation requires no debugging

Description
It uses pure PWM signal speed control to prevent stuttering and abnormal noises caused by intermittent power supply. When the wire is connected to the negative terminal, the fan operates at minimum speed (approximately 20%, without shutting down)
Specifications
Operating Voltage: 12V, 24V
Control Method: Temperature-controlled speed regulation
Maximum Output Current: 5A
Instructions for Use
This speed controller is designed to enter minimum speed at a fixed temperature of approximately 23C. The maximum temperature for maximum speed is set via DIP switches within the range of 43-70C;
When all DIP switches are off, the maximum speed temperature is 43C, and the fan operates at stepless speed control between 23C and 43C;
When the first is set to the (0N) position, the maximum speed temperature is 52C, and the fan operates at stepless speed control between 23C and 52C;
When the first is off and the second is , the maximum speed temperature is 61C, and the fan operates at stepless speed control between 23C and 61C;
With both channels 1 and 2 activated, the maximum operating temperature
